Do You Really Understand Life-Saving Mandatory Equipment - Bulletproof Vest?

There are regulations for the mandatory equipment of mountain bike off-road, which is the equipment that must be carried. As an important hardware in the mandatory equipment - the windbreaker, it is not only a necessary product for athletes to deal with sudden extreme weather in the mountains, but also the preferred equipment for many outdoor activity participants. However, as an equipment that can save lives during critical moments, do you really understand it?

What kind of equipment is the windbreaker that uses PTFE composite fabric?

The windbreaker, also known as the Outdoor Jackets, originated from Europe and America and is one of the necessary equipment for outdoor sports. Different from ordinary jackets, the windbreaker has all-weather windproof, waterproof, and breathable functions, which makes it the first choice for outdoor enthusiasts.

In order to be considered a qualified windbreaker that can cope with all-weather outdoor activities, it should meet certain standards. 

Firstly, it must be 100% waterproof. This means that it can effectively prevent wind, frost, rain, and snow from entering whether you are sitting in a damp place or walking in a stormy environment.

Secondly, it must be 100% windproof. As a kind of windproof membrane, the unique three-dimensional nano-microporous structure of PTFE can effectively block the cold wind from outside and regulate the temperature of the body surface to maintain comfort. 

Thirdly, it must be breathable. When people exercise outdoors, their bodies naturally sweat and exhale a lot of moisture. If it cannot be quickly expelled from the body, sweat will become trapped between the body and clothes. In extreme cold conditions, if the body stays wet for a long time, it will cause the body to lose heat and endanger life. Therefore, good breathability of the clothing is very important.

How is the windbreaker that uses PTFE composite fabric made?

The advantages of PTFE membrane are: chemical properties of polytetrafluoroethylene membrane are extremely stable, with high and low temperature resistance, corrosion resistance, and weather resistance, and it has good protection. Even under ±190℃, it will not change. 

The diameter of the pores on the PTFE membrane is about 400 times that of water molecules and 1/40000 of water droplets. There are about 9 billion micropores per square centimeter, which makes it impossible for water droplets to pass through, but sweat can be discharged through the micropores, achieving the purpose of waterproof and breathable. Then, this thin film is laminated with fabrics to form the windbreaker fabric that we usually see.

The principle sounds simple, but it is difficult to master the core technology such as how to control the pore size, density, and uniformity during the stretching process. The difficulty coefficient and process level of the product determine its price. As a professional PTFE film manufacturer, Yutian can customize various professional (military, police, fire protection, workwear, medical) protective textile products.
